FIRE-EXTINGUISHER FOR CAR-STOVES.

SPECIFICATION forming part of Letters Patent No. 424,743, dated April 1, 1890.

Application filed November 22, 1889- Serial No. 331,175. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL S. WEINBERG, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Fire-Extinguishers for Car-Stoves, of which the following is a specification.

This invention relates to a fire-extinguisher for car-stoves.

The object of the invention is to provide means for extinguishing the fires in car-stoves, which means will be operated automatically upon the occurrence of certain accidentssuch as collisions or derailments-and the operation of which also may be under the con trol of the engineer.

The invention is illustrated in the accompanying drawings, in which-- Figure 1 is a vertical longitudinal section of part of a car with astove and my improvements. Fig. 2 is a horizontal section through the top part of a car on the line 2 2. Fig. 3 is a View of a car-stove and the principal parts of the extinguisher. Fig. 4 shows two views of one of the circuit closers. Fig. 5 shows a part of a car and part of a locomotive in sec tion, and the wiring which connects the circuit-closers on the car with a push-button in the cab of the locomotive;

The letter A designates the car; B, the cab of the locomotive; C, the stove or heater of any desired pattern or any well-known kind, and (Z, the stove smoke-pipe.

I provide a glass receptacle e, adapted to be readily broken and support it in an inclosure f at a point elevated above the stove. The inclosure may have a funnel-shaped bottom f, and a pipe f leading down therefrom and entering the stove. The lower end of this pipe is closed or guarded by a flap-valve g to prevent the entrance of dust or cinders. A fireextingnishing solution is to be contained in the glass receptacle 6, and when the latter is broken said solution will flow down the pipe f past the flap-valve g and into the stove and put out the fire. A spring-actuated hammer will break the receptacle.

I also employ a fire-extinguisher to contain, separately, an alkaline solution and an acid which are to be mixed and directed into the stove when the contingency arises calling for their use.

The letter h designates a receptacle for the connecting with the bottom of the stove. the top of this receptacle h is supported a glass acid-receptacle 7s. When this is broken, the acid will mix with the alkali and produce carbonic-acid gas, like ordinary chemical fireand put out the fire. A spring-actuated punch-rod at will break the receptacle.

The pivoted hammer Z to break the glass gage it from the hammer or punch, whereupon the latter devices will strike the glass receptacles and break them.

The circuit-closers t consist of two bronze ported on a stud u.

A push-stud 1; passes through the car-wall, and a bar or rail 10 on the outside is attached to the push-stud. One rail to may be thus attached to several push-studs r. normally keeps the push-stud outward and prevents its end from pressing the two bronze plates t together, and thereby closin the circuit.

each of the circuit-closers ton the car is connected by one of the wires .9 s, leading from one pole of the battery 0'. The other plate of each of the circuit-closers t is connected by q q. The wire passing from this electro-magnet leads to the other electro-magnet, from which the other wire .9 8' passes to the other pole of the battery 1*. The space between the an open circuit.

I prefer to place the rails 10 at the top of the car and at the end and sides thereof, as shown, By this arrangement, when a collision occurs alkaline solution, having two curved pipes 71 c extinguishers, and the gas and liquid spray 6c will be forced out of the pipes -i into the stove receptacle e and the sliding punch m to break A springp .the magnet it will draw the hook and disen- 7 5 plates overlapping each other, and each sup- A spring a A battery 7' is on each car, and one plate of a wire leading to one of the electro-magnets pair of plates of each circuit-closer 25 provides or a car leaves the track or rolls over, the fireextinguishers will be actuated automatically. I also run the Wires to the cab of the locomotive and connect them with a circuit-closing push-button 3 By this arrangement the engineer may, on perceiving that a Wreck is imminent, operate all the fire-extinguishers.

Having described my invention, I claim- 1. The combination of a car-stove, a fire-extinguisher, a pipe leading from the fire-extinguisher to the stove, a spring-actuated device I to operate the fire-extinguisher, a battery, circuit-closers, Wires connecting the battery circuit-closers and the said spring-actuated device and making an open circuit, and a bar or
